Adaptation actions to reduce water system vulnerability to climate change in Tensift River basin (Morocco)

Abstract. The Human Dimension of the Twinning European and South Asian River Basins to Enhance Capacity and Implement Adaptive Management Approaches Project (EC-Project BRAHMATWINN) is aimed at developing socio-economic tools and context for the effective inclusion of the "Human Dimension" or socio-economic vulnerability into the overall assessment of climate risk in the twinned basins of the Upper Brahmaputra River Basin (UBRB), and the Upper Danube River Basin (UDRB) . This work is conducted in the light of stakeholder/actor analysis and the prevailing legal framework. In order to effectively achieve this end, four key research and associated activities were defined: 1. Identifying stakeholders and actors including: implement an approach to ensure a broad spread of appropriate stakeholder input to the assessment of vulnerability undertaken in Asia and Europe within the research activities of the project. 2. Contextualising legal framework: to provide an assessment of the governance framework relating to socio-environmental policy development within the study site administrative areas leading to the specific identification of related policy and legal recommendations. 3. Spatial analysis and mapping of vulnerability: providing a spatial assessment of the variation of vulnerability to pre-determined environmental stressors across the study areas with an additional specific focus on gender. 4. Inclusion of findings with the broader context of the BRAHMATWINN risk of climate change study through scenarios of hazard and vulnerability (subsequent chapters). This study utilises stakeholder inputs to effectively identify and map relative weightings of vulnerability domains, such as health and education in the context of pre-specified hazards such as flood. The process is underpinned by an adaptation of the IPCC (2001) which characterizes Risk as having the components of Hazard (physiographic component) and Vulnerability (socio-economic component).

Central Chile

Water management systems have been typically designed and operated under the assumption of stationarity. This assumption may no longer be valid under climate change scenarios. Water availability may change dramatically at some locations due mainly to possible impacts of changes in temperature and precipitation over streamflow volume and seasonality, adding pressure to water supply systems. It has been shown that snowmelt-dominated basins are particularly sensitive to such changes. Hence, human settlements and economic activities developed in such areas are particularly vulnerable. The Maipo river basin in Central Chile – where more than 6 million people live – is one of these areas. We used a calibrated water resources model of the Maipo river basin, in order to propose a general framework to evaluate adaptation options at the urban level. When comparing a mid-21st century period to a historic control period, results for three selected performance metrics showed a decrease in water system performance. Adaptation measures were evaluated in their capacity to maintain current water security standards. Two alternatives stand as highly effective options to this end: water rights purchases and improvements in water use efficiency. The political and economic costs of implementing these options, which could deem them unviable, are not considered here but are worthy of further research.

The Impact

According to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, warming of the climate system is unequivocal and in recent decades, changes in climate have caused impacts on natural and human systems on all continents and across the oceans. Surface temperature is projected to rise, and rainfall patterns to change. Freshwater resources could be compromised due to climate change, especially in the Mediterranean region. Moreover, extreme events as droughts or floods are expected to occur more frequently.For all these reasons, we propose the evaluation and implementation of a climate change adaptation river basin plan with the aim of reducing risks and improve resilience. Indeed, one of the goal 13 targets of the Sustainable Development Goals is strengthening resilience and adaptive capacity to climate-related hazards and natural disasters in all countries. The EU Strategy on adaptation to climate change encourage all members to implement adaptation strategies. For instance, climate change adaptation river basin plans are a reality in France, where basin adaptation plans have been published since 2014.Evaluating risks and propose measures in order to reduce water vulnerability is needed in Jucar river basin (Eastern Spain) where water system is currently stressed. Jucar climate change adaptation basin plan should evaluate the specific qualities the basin has and the risks and vulnerabilities in order to strength water management. For this evaluation, we propose to assess the impact of the spatial distribution of precipitation and temperature within the case study for identifying the most vulnerability areas. Furthermore, the sea level rise will cause affection in groundwater aquifers that should be included on the proposed analysis.

Vulnerability To Climate Change

The Intergovernmental Panel on Climate Change (IPCC) suggests that vulnerability to climate change depends on three main factors: exposure, sensitivity and adaptive capacity. Each factor was evaluated in a hydrologic context, for instance exposure was interpreted as a change in surface runoff. Factors were combined using a Geographic Information System (GIS) and an overall methodology to map hydrologic vulnerability was proposed. The Conchos River Basin, which is the main tributary of the Rio Grande, was used as a case study. The long-term rate of change in surface runoff was estimated considering the variation in future precipitation from 23 Atmosphere-Ocean General Circulation Models (AOGCM) by using the Reliability Ensemble Averaging (REA) method. Two climate change scenarios (A1B and A2) and three time horizons (2030, 2050 and 2100) were chosen. Results showed a decrease in surface runoff up to 28% (A1B-2100) north of the Basin. Hence, it is likely to have more frequent droughts. However, it would be challenging to compensate the lack of surface runoff since groundwater resources are already depleted. Finally, overall hydrologic vulnerability maps were obtained to locate the most vulnerable regions, where precisely adaption efforts would be more necessary to sustain environmental conditions.
